Question

(a²b½) ¼ / a½b9 / 8 please help with a = 7, with b = 2

Answer 1

Answer:

The correct answer is 0.5

Given:

a = 7 , b = 2

To find:

(a²b½) ¼ / a½b9 / 8

Solution:

= (a²b½) ¼ / a½b9 / 8

= (a²*¼  b½* ¼ )/ a½b9 / 8

= (a½ $b^{1/8}$) / a½$b^{9/8}$

= $(b^{1/8} ) / (b^{9/8} )$

= $b^{1/8 - 9/8}$

= $b^{-1}$           -------------------(b=2)

= 1/2

= 0.5
